Some simple correlations have been developed for
estimating characteristic drop sizes based on a few
experiments [3–5]. These correlations can be used as
primitive predictive models; however, they have a limited
range of validity and are insensitive to many effects that are
known to influence the initial spray behavior. The data in
these correlations are obtained under quiescent ‘cool’
conditions. However, the elevated velocities and temperatures
in real fires are expected to influence the atomization
process. A robust physics-based approach capable of
handling this coupling has been used to develop the
atomization model in this study.
